Frequently Asked Questions
What makes the Tiger Eye contact in the SFM-110-02-L-D-K-TR different from standard board connector contacts?
The Tiger Eye contact is a proprietary SAMTEC design that provides lower insertion force than conventional stamped contacts while maintaining reliable electrical contact over extended mating cycles. This design reduces connector wear, allowing reliable operation through 200 or more mating cycles. The 10 µin gold mating finish further ensures stable low-resistance contact in signal-critical applications.
How does the dual-row 20-position layout of the SFM-110-02-L-D-K-TR benefit high-density PCB designs?
With 20 contact positions arranged in 2 rows of 10, the SFM-110-02-L-D-K-TR carries twice the signal density of a single-row connector in the same board footprint length. This is valuable in embedded computing and telecom boards where routing 20 signals through a compact connector saves board space and reduces PCB layer count compared to using two 10-pin single-row connectors.
When is the SFM-110-02-L-D-K-TR a preferred choice over lower-cost board connectors without gold plating?
The SFM-110-02-L-D-K-TR is preferred in applications requiring long service life with repeated mating cycles, such as test fixtures, modular industrial controllers, or field-upgradeable daughtercards. Its 10 µin gold mating finish resists oxidation and maintains contact resistance below 20 mΩ over the connector's lifetime. For lower mating frequency, tin-finished alternatives may suffice, but gold plating is the correct choice when signal reliability over hundreds of cycles is critical.
